The present invention provides 55 a box in which a closure may be formed by sevcring portions of the box from the body thereof when it is desired to open the box which closure may be repeatedly reapplied whenever desired.

My invention as best shown in Fig. 2 consists of an outer shell III covered by a suitable wrapper I I. Within the shell I9 is disposed arsleeve I2. The shell `,I0 is weakened along certain lines to permit of severing the upper portion of the said shell from the body portion thereof to form a closure I3 for closing the upper end of the box. 'I'his closure cooperates with the sleeve I 2 to form a seal and may be repeatedly used as the occasion demands. These parts will now be described in detail.

'Ihe shell III is constructed from a blank indicated in its entirety at I4 in Fig. 5, which blank is constructed from a sheet of paper board or any other suitable material. The blank I4 is substantially rectangular and is provided with two longitudinal score lines I5 and I6 and with transverse score lines I1, I9, I9 and 29 extending between the score lines I5 and I6. 'I'hese various score lines divide the blank into a rear wall 2|, a front wall 22, side walls 23 and 24 and a ap 25 issuing from the front wall 22. 'I'he blank I4 is further sheared along lines 26, 21, 28, 29, 30 and 3| and the corners of the' blank cut away as indicated at 32 and 33, which lines of shear lie in continuation of the score lines I1, I6, I9 and 26 and extend up to the score lines I5 and I6. By means of this construction, flaps 34, 35, 35, 31, 33, 39, 45 and 4I are provided-which,'when properly folded, form ends 42 and 43 for the box.

For the purpose of forming the closure I3, the

' rear wall 2| of shell I5 is providedwith a score line 54 which is parallel to the score line I5 and spaced a short distance therefrom. In addition to this score line the front 22 and the sides 23 and 24 are weakened along lines 55, 55 and 51. which lines lie in continuation of the score line 54 and are also parallelto they score line I5 and spaced the same distance therefrom as the score line 54. The lines 55, 56 and 51 may be formed by perforating the sheet or by otherwise deforming the sheet fas by completely shearing the same along defined portions thereof or by cutting or incising the sheet partly through the same to provide a continuous line of weakening or spaced apart indentations. When the box is formed, the shell I5 thereof may be broken along the lines of weakening 55, 56 and 51 to form the closure I3 which may be swung upon the score line 54 as a hinge as best shown in Fig. 2.

'I'he sleeve I2 is similarlyL constructed from a blank 44 preferably formed of paper board or other similar material. This blank is rectangular in form and of a height slightly less than the distance between the score lines I5 and I6 of the blank I4. The blank 44 is scored along transverse lines 45, 46, 41 and to provide a rear wall 49,` a front wall 53 and side walls 5I and 52 and a flap 53 connected to the front wall 50. The score lines y45, 449 land 41 and 45 are slightly closer together thanv the score lines I1, I6, I9 and 25 so that the walls 49, 555I and 52 flt snugly within the walls'2I, 22, 23 and 24 when the two blanks are properly folded and connected.

In the construction of the box glue or other adhesive such as indicated at 56 is applied to the rear wall 2l of the shell Il upon the interior surface thereof or upon the sleeve I2 upon the exterior of the corresponding wall thereof. 'This glue is disposed inwardly of the score lines I1 and I3, above the score line I 5 and in proximity to the score line 54 and immediately below the same. The blank 44 is applied to and secured to the blank I4 through the glue 56 which adheres to the rear wall 49 of said blank. In positioning the blank 44 upon the blank I4 the rear wall 49 Lis exactly centered upon the rear wall 2|, the score lines 45 and 46 falling slightly inwardly of the score lines I1 andv I9. This brings the score lines 41 and 49 progressively inwardly from the score lines I9 and 29 as clearly shown in Fig. 7. With the blanks so arranged, flap 53 overlies flap 20 and extends outwardly beyond the same. When the blanks are in such position, glue is simultaneously applied to both the flap 29 and the portion'of the flap 53 extending beyond the same. `In the further construction of the box the attached blanks are folded along the score lines I9 and 41, bringing the fronts 55 and 22 over upon theremaining structure of the box. As these parts 'are`i'olded, the flap 25 creeps away from the glued part of the flap 53 separating the glued portions of said flaps which prevents the end wall of the sleeve from adhering to the end wall of the shell. The side walls 23 and 5I are next folded upon the glued flaps 25 and 53 which causes' the said side walls to be attached to the front walls of the shell and sleeve. The box is then in collapsed form with the walls at the ends of the blank connected together.

In the erection and illling of the box an ordinary filling machine is employed such as is used with similar boxes or cartons. This filling machine is constructed with two blades which are inserted between the folded-over portions of the box; said blades being subsequently spread apart to cause the body of the box to assume a rectangular form. As the box passes through the filling machine the box is arranged upon a suitable form and the flaps 35, 39, 45 and 4I folded over and glued together to form thev end 43 of the box. The contents of the box are then placed within the same. Where certain kinds of substances are to be packed, such as flour, sugar and the like, the same are preferably placedv in a bag such as indicated at 59 in Fig. 3, and said bag inserted into the box through the openv upper end thereof. Flaps 34, 35, 36 and 31 are thereafter 'folded over and glued together to form the end 42 of the box. The contents are now completely enclosed through the wall structure of the box. After the box has been closed, the wrapper is applied which is formed from a plain sheet of paper, the ends thereof being folded over and glued to the end of the box and to themselves as indicated at 65 in Fig. 1. 'I'he wrapper II has printed-upon it lines 52 and 63 which when the wrapper is properly applied, register with the lines of weakening 55, 56 and 51 in the various walls 23, 24, and 25 of the shell III. When it is desired to open the box, a knife or the finger nail may be run along the lines 52 and 63 breaking the walls of the box along the lines of weakening 55, 56 and 51. After the vbox has been so broken the closure I3 is `formed which may be swung outwardly as shown in Fig. 2 to give access to the substance packed within the box and contained within the bag 59.

For the purpose of preventing the contents 'of the box from entering between the upper part of the sleeve I2 and the portion of the closure I3 formed through the rear wall 2|, of the shell tol obstruct the closing of the closure, the upper portion of the rear wall 49 of sleeve I2 is constructed withl a recess or opening 64. I'his opening extends downwardly from the upper edge 65 of the blank Il to a line It which is adapted to substan-4 tially register with the score line I4 of blank Il when the blank M is secured to the blank Il or to lie slightly below the same. Any material which may fall in between these two parts of thea? box is readily forced out through the opening what is claimed without departing from the spirit of my invention.

Having described my invention, what I claim as newand desire to protect by Letters Patent is:

i. In a box, a shell including front. back and `side walls and ends connected therewith, one of 64 and into the interior of the box. In applying aid walls being scored along a transverse line of the blades of the filling machine to the collapsed box, the -same are preferably run along the flap 35 and directed into the interior of the box through the wall structure connected therewith. By means of the cut away portion M the blank M is securely glued to the blank Il at the locality of the score line 54. This permits the blade of the filling machine to slide over the edge Il of the blank M and to be received within the interior of the collapsed box. Were the portion of the wall 49 of sleeve I2 of the same height as the walls of the box, the blades of the filling machine might easily slide in between these parts of the carton which must of necessity be free from one another to permit of the subsequent hinging of the closure when the same is severed from the body of the box. By means of this recess or opening the blades of the filling machine readily enter into the interior of the collapsed box and the opening and subsequent forming and filling of the box is accomplished in identically the same manner as with the ordinary box or carton blank.

It will be noted in Fig. 4 that the flaps formed on the shell and sleeve extend from adjacent corners of the box toward one another and that the same are of such width that the flaps fall short of one another when the parts are glued together. 'I'his causes the flaps to lie in the same plane in oifset relation with respect to one another, thereby not materially increasing the thickness of the box. By gluing the sleeve to the shell along one wall, the other walls of the sleeve and shell slide relative to one another permitting the box to be readily erected or collapsed as desired.

It will be noted in Fig. 'l that the flap I3 and the ap 25 are bothof the same length and of a length equal to the height of the walls of the carton to which they are attached. By means of this construction a glue roller can be run continuously along such flaps and the glue applied without coating any other portion of the blank.

My invention is highly advantageous in that a reclosing box or carton can be formed from an ordinary carton with but a slight additional cost. With my invention greater sanitation is brought about and preservation of the contents of the box results. With my invention the box blank can be erected and formed and filled upon the ordinary filling machine without reconstruction or alteration thereof. With my invention the contents of the box are fully protected the same as in any other form of box. 'I'he boxes prior to erection can be folded into a flat form the same as ordinary boxes and packed and shipped in the customary manner. By arranging the joints of the sleeves and shell in staggered or offset relation no appreciable additional thickness is provided and the parts ofthe carton fold readily in the desired manner. Through the use of the opening or recess in the sleeve of the box adjacent the hinge of the closure, portions of the contents which may fall between the closure and sleeve are caused to be discharged back into the box. At\

the same time the insertion of the blades of the `filling machine into the box is greatly facilitated.

Changes in the specific form of my invention, as herein disclosed,may be made within the scope of spacedfrom one end thereof, the remaining walls being weakened along lines lying in continuation of said score line and one another to provide a closure partly severable from the body of the box and a wrapper enveloping said box and overlying the weakened portions of the shell, said wrapper having lines printed thereon and registering with the lines of weakening of the shell. l'
